What Caldereria Oslan does
Caldereria Oslan (legal entity: Calderería Oslan S.L.) is a family-owned metal fabrication business based in Legazpi, Gipuzkoa, Spain, specializing in carbon steel structural components and medium steel boilermaking (calderería media). The company manufactures metal structures for engineering firms, producing monolayer, spatial, embedded, and support structures to customer-supplied blueprints, and operates both serial production and custom one-off work. Its customer base consists of engineering companies running construction and industrial projects at national and international levels.
Production is carried out at a 2,100 M2 indoor pavilion with a 12,000 M2 outdoor yard, combining traditional calderería machinery with a FANUC welding robot fitted with dual 6-meter tables for automated precision welding of large structural assemblies. The firm has been CE-marked since 2015 under EN-1090-1:2009+A1:2011 execution class EXC3, and all welding procedures and welders are homologated to that standard; the welding coordinator is certified by CERTIAEND for magnetic particle inspections at Level 2.
Commercially, Caldereria Oslan runs a quote-based, project-driven B2B model with no published pricing, marketing itself as a flexible small shop able to adapt to engineering specifications rather than as a standardized catalog vendor. Distribution is direct to engineering project sites in Spain and abroad. The company has 11-50 employees, no parent organization, no disclosed investors, and no digital presence beyond a corporate website and basic social media profiles.

Caldereria Oslan product offering
Product offeringCore offering
Caldereria Oslan manufactures custom metal structures and carbon steel components for engineering firms. The company produces monolayer, spatial, embedded, and support structures through both serial production and custom work-to-blueprint fabrication. Operations are CE Marking certified under EN-1090-1:2009+A1:2011 execution class EXC3 since 2015, and leverage a FANUC welding robot with dual 6-meter tables for precision welding.
Product overview
Caldereria Oslan is a small family-owned metal fabrication company specializing in medium steel boilermaking (calderería media). Their core offering centers on metal structure fabrication in carbon steel, delivered through three interconnected services: standard metal structure fabrication (Estructura Metálica) producing monolayer, spatial, embedded, and support structures for engineering projects; custom carbon steel structural component manufacturing; and specialized custom fabrication services under blueprint specifications. The company serves primarily engineering firms for both national and international projects, leveraging automated FANUC welding robotics alongside traditional fabrication machinery.

Caldereria Oslan competitors and assessment
Company assessmentDirect peers
- William Hare: UK-based structural steel fabricator serving construction and engineering projects with bespoke and serial capacity — a closely comparable custom structural steelwork supplier with similar B2B engineering-firm customer base.
- Zeman Group: Austrian family-owned specialist in steel halls and structural steel construction with EN 1090-certified fabrication — a similar certified family-fabricator business model serving engineering and construction clients across Europe.
- Severfield: UK-listed structural steel fabricator for buildings and infrastructure projects — directly comparable certified structural steelwork serving engineering- and contractor-led projects.
- Voortman Steel Group: Dutch automated steel processing and fabrication group whose robotics-driven structural steel production and CE-marked output directly mirror Caldereria Oslan's robotic structural steelwork for engineering and construction clients.
Others
- Tubacex: Spanish-listed stainless steel tube and steel products group based in the Basque Country — adjacent Spanish steel specialist sharing the regional labor pool and industrial customer ecosystem, but not a direct fabrication competitor.
Broad incumbents
- CIE Automotive: Spanish-listed industrial group with metal components and structural activities — a broadly comparable Spanish industrial base, though far larger, more diversified and more automotive-focused than Caldereria Oslan.
